Abstract
It is shown that the dynamics of spiral waves in excitable media are organized around a codimension-two point where a Hopf bifurcation from rotating waves interacts with Euclidean symmetry. A simple ordinary-differential-equation model of this bifurcation generates dynamics like the ‘‘meandering’’ of spiral waves.
